Abstract
The invention discloses a gear set of a miniature gear pump working stably. The gear set comprises two engaged gears. The two gears are the driving gear and the driven gear respectively. The gear set is characterized in that the two gears are involute straight gears; parameters of the two gears are the same; the tooth number of each gear is 10, the modulus of each gear is 1, the pressure angle of each gear is 27 degrees, the tip diameter of each gear is 12.7 mm, the reference diameter of each gear is 10 mm, and the root diameter of each gear is 8.37 mm. The invention further discloses a machining method of the gears. The gear set of the miniature gear pump is improved, the machining method of the gears in the gear set is improved, the gear pump works stably, oil leakage and oil trapping phenomena are reduced, and the operating life is prolonged.
Description
technical field [0001] The invention relates to a gear set for a micro gear pump, in particular to a stable working micro gear pump gear set and a gear processing method. Background technique [0002] Gear pumps are called positive displacement devices, which are widely used in industrial and agricultural production. The micro gear pump is a smaller and more precise type of gear pump. A micro gear pump consists of a set of intermeshing driving and driven gears. The driving gear and the driven gear are generally the same gear, and the structure, number of teeth, modulus and other parameters of the two directly affect the working effect and service life of the gear pump. In the existing micro gear pump, due to the unreasonable design of the gears and the lack of gear precision, the meshing degree is not good, the vibration is large, the noise is large, and even the phenomenon of oil trapping and leakage occurs; moreover, it is not suitable for Low-viscosity media (such as w...
